Summer: August to April is hot peaking in September & October. (November to February
is the rainy season and can be very warm, so be sure to bring cool clothing
and raincoats

The winter months (May to August) are dry which is good for game-viewing
but make sure to bring very warm clothing / jackets for the night drives as the cloudless skies can reduce temperatures to zero at night. Daytime temperatures are wonderful
